Some Important Terms of RD Sharma Solutions Class 11 Chapter 2 Relations (Ex 2.1) Exercise 2.1

Ordered Pairs

The two sets namely Set Y and Set Z include an ordered pair of (y, z). Due to the presence of the first elements, one of the sets is known as primary sets from Set Y and Set Z, whereas the second one is referred to as the second set and includes secondary elements. These ordered pairs are commonly used for Cartesian products and Relations.

Cartesian Product of Two Sets

The set of all probably ordered pairs lying in between the two sets adhering to a sequence is called the Cartesian product of two sets. This is represented as Y X Z or Z X Y where both Y X Z Z X Y are written completely differently.

Domain and Range of Any Relations

The set of primary elements of ordered pairs is referred to as the Domain of a Relation represented by Relation R from Set Y to Set Z. Whereas, on the other hand, the set of secondary elements of the ordered pairs is referred to as the range.

The Inverse of a Relation

It is simply known as the opposite of any Relation represented as R^-1
